Improvement in stencils



UNITED STATES PATENT OFFICE.

R. A. ADAMS, OF ST. LOUIS, MISSOURI.

IMPROVEMENT IN STENCILS.

Specification forming part of Letters Patent No. 22,272, dated December14, 1858.

To all whom it may concern:

Be it known that I, Bonner A. ADAMS, of the city andeounty of St. Louis,and State of Missouri, have invented a new and Improved Method ofGraining in Oil; and I do hereby declare that the following is a full,clear, and exact description of my said invention as prepared andapplied by me.

My invention consists in the preparationof a stencil in a given way foragiven purpose,

and as the said preparation consists in the application of certainwell-known chemical simples to the stencil the case cannot beillustrated by a drawing; but the following description will enable anyone skilled in the arts to make and use myinvenlion without furtherreference.

The body of the stencil is of paper, or it may be made of any knownsubstitute, which is first soaked in shellac and oil, the proportions ofwhich must be regulated by the amount of stiffening required in thestencil. After the stencil-blank has been thus soaked in shellac and oilthe back of it is coated with glue, to which a coating of sand or emeryis applied, after which it is allowed to dry, which coinpletes thestencil-blank.

Now,let it be desired to imitate the grain of oak. The blank stencilafter having been prepared as above described, is cut into figures tocorrespond with the grain of a piece of oak wood, after which it isoiled on both sides, which fits it for use. Now let the ground of thework be prepared and the coloring laid on in the ordinary way. Thestencil is then laid against the work thus prepared, with the sandedside next the paint. Then with a cloth the color is rubbed out throughthe openings in the stencil which form the figures, which completes theoperation.

Stencils have been used to grain with before, but never in oil, which isentirely different from grainin g in water-colors. An ordinary stencillaid against a piece of fresh oil painting would cause it to run andblur the work, so as to spoil it; but by preparing the stencil in themanner described, and by applying the sand or emery to the back of it,the surface of the stencil is prevented from coming into absolutecontact with the face of the work, and consequently prevents the workfrom being blurred or in any way soiled, but leaves the figures intendedto represent the grain of the wood sharp and proper. It will thus beseen that without the application of the sand to the back of the stencilit could not be used to grain in oil and it will also be seen thatunless the stencil was prepared with the shellac, oil, and glue, orsomething similar, it could not be made of paper, nor, indeed, of anyother manufacture, as it would not have the necessary stiffness andhardness.

The preparation of the stencil-blank, then, in the manner described, andthe application of the sand or emery to the back of it, as set forth,are what constitute the essential features of my invention.

What I claim, therefore, and desire to secure by Letters Patent, is-

l. The preparation of the stencil-blank in the manner describedto wit.,in oil, shellac, and glue, applied as set forth.

2. The application of the sand or emery to the back of the stencil, inthe manner described, for the purpose specified.

R. A. ADAMS.
